This study aims to analyse food sovereignty strategies in an effort to eradicate poverty in a micro-scale region by strengthening its food security status. The research was conducted in the Kutai Kartanegara District East Kalimantan Province in Indonesia. Food insecurity status in the study area was determined based on nine food security indicators. The 237 villages in the Kutai Kartanegara District were ranked based on four classifications of vulnerability to food insecurity. The results showed that 3.80% of the villages were highly vulnerable, 5.06% were vulnerable, 8.86% were slightly vulnerable and 82.28% were food secure. While Kutai Kartanegara was a food secure district, in order to maintain its food security status and enhance the performance of the villages that are still vulnerable to food insecurity, local government, and related stakeholders must work together to develop strategies to improve agricultural productivity, increase the region’s human resources capability and strengthen its infrastructure so food can be more readily accessed.

Lake Rawa Pening is a natural lake in the Semarang Regency of Central Java Province, Indonesia, and its existence is pivotal to the surrounding communities as it provides ecological, economic, and social benefits. The ecosystem health of Rawa Pening can be represented by chlorophyll-a concentration because it indicates phytoplankton biomass, nutrient availability, and fish resources. Hence, the present study aims to disentangle the monthly variability of surface chlorophyll-a in Rawa Pening Lake by analyzing water samples that were collected once a month from nine stations within five-month observations (September 2020 to January 2021). The samples were analyzed using spectrophotometric method. Results showed that the highest surface chlorophyll-a concentration (23.33 mg/m3) took place in December, while the lowest concentration (12.64 mg/m3) occurred in October. The monthly variability of surface chlorophyll-a was likely controlled by variation of rainfall, with the highest (18.72 mm) and the lowest (12.33 mm) rainfall happened in December and October, respectively. The present study also indicates the anthropogenic activities such as agricultural activities, floating food stands, aquaculture, and tourist boats may contribute to surface chlorophyll-a variability in Rawa Pening Lake.
